Yep, course is in Streetsboro, OH and can be seen from OH Turnpike. Price is high, but it is one of the nicer tracks anywhere in NE Ohio. Very much 'target-golf' track.
I did not see the disclaimer on the website. The only time my golf mates and I will play there is when they drop the rates to around $50 later on a Saturday or Sunday. No special rates to be had and the price increases as the week moves toward weekend.
My guess is they have a good number of regulars who snag up the early tee times regularly on Sat and Sun mornings. The disclaimer comes off a bit 'elitist' to me. There are a couple of other courses like Windmill Lakes in Ravenna and Seven HIlls in Hartville where it's difficult to even get an early weekend tee time due to 'regulars' who are afforded regular standing early tee times. We tend to shy away from the courses with such policies.
Assuming the Ping Zing are actually suited for your swing (shaft, lie etc), I wouldn't change the set because those are a really nice set of irons. But the key is getting fitted and then picking a set of clubs that suit the specs, preferably in SGI or GI
Looking for new or used? Cheap or money doesn't matter?
Im a newb and have no experience to share. I found this review article a good introduction to the new options out there. It also helps you get familiar with the options and allows you to do some searching for the older versions of the clubs noted
